      I'm sure this answer is buried somewhere and I'm just not seeing it.  I've written a script to count the number of records in a text file and return the count via WScript.Quit(<recordcount>).  The .BAT program that calls the script then checks %ERRORLEVEL% to see how many records were in the file and continues with processing.
      My question:  how large can the integer value be for WScript.Quit() and %ERRORLEVEL%?  I've used this method for fairly large files, but want to know if I'm in danger of trying to count records using this method in a file that is too large.

      In older MS OSs the ERRORLEVEL was a single byte.  Therefore the maximum value was 255.  However, with the advent of WinNT4 and beyond, the ERRORLEVEL is now stored as a Long - that is, a four byte, signed integer; yielding maximum and minimum values of 2147483647 and -2147483648, respectively.

      In other word, unless you have more than 2 Billion records in a file, you should be in good shape.
